Addition using function involving array

[TruefreeWorld]

I know there are some serious issues with this program, please help correct it.

What I want the program to do is to scan an array of numbers and use function to calculate the sum

/"Program to enter a list of number and perform their addition using function"/


#include<stdio.h>


int addn(int b[])


{
int i=1;  /"initialize i to 1"/


int sum=0;


sum+= b[i];


return sum;


}




main()
{


int j, n, a[20];
int result;
printf("Enter the count of numbers to be added:\n");


scanf("%d", &n); /"The 


for(j=1;j<=n;j++)
{
scanf("%d", &a[j]); /"number input"/


printf("Entered numbers are: %10d\n", a[j]);   /"Display the entered numbers"/


printf("Performing addition\n");


result= addn(a);
}


printf("The sum is :%d", result);  /"Display the result"/


return 0;


}

> result= addn(a);
1. Add the n parameter, so result= addn(a,n);

2. Move it down a line, so it's no longer part of the for loop in main.

3. Put another for loop inside addn() to iterate over your array elements (that's why you also need n).
